OK can you explain to me the interest of using private keys if you publish them afterwards?? I'm missing something..

  The recipient knows you sent the message, because they received it before you published the key. Nobody can prove you sent the message, because they received it after you published the key, and even if they did receive it earlier, they can't prove it in court. That's why the key should be published as soon as possible. In a point-to-point protocol, it would be published as soon as the recipient confirms receipt of the message. That's why I'm not sure how it generalizes to group chat protocols.

  They attest you are the author between the publication of the message (and of the public key) and the publication of the private key.
